Model access is the start.
Product controls are the difference.
Define what “best” means for your use case
Merge
Gateway scores eligible models against the criteria your product requires
- Use published benchmarks
- Add your own eval scores
- Weight criteria by use case
- Train complexity routing on your prompts
OpenRouter
OpenRouter selects models by task, community spend, and cost-quality. For tool calls, its benchmarks rank providers. Your scorecard cannot drive selection.
- No customer-supplied benchmark scorecard
- No routing from customer eval scores
- No weighted mix of customer quality criteria
Configure routing around your product
Merge
Gateway learns what complexity means for your product before it selects a model
- Train on your own prompts
- Score each prompt before model selection
- Retrain as your product changes
OpenRouter
Custom classifiers tag completed requests for reporting
- No customer-trained routing classifier
- Custom classification runs after the response
- Custom tags inform reporting, not routing
Give every customer their own model controls
Merge
Gateway lets you provision every one of your customers with first-class controls

Capability |  | OpenRouter |
|---|---|---|
Custom routing policies |  Tag requests by customer tier, region, or use case, then route on AND/OR rules |  Sorts by price, latency, or throughput. No rules by customer tier, use case, or custom criteria. |
Benchmark routing | Gateway evals every model against benchmarks you define, then routes to the winner | No custom benchmark routing. Model selection limited to built-in sort criteria. |
Request visibility | Every request logged: model, routing decision, latency, and cost | Usage tracked by model and API key. Routing decisions not included by default. |
Embedded routing control | Provision routing policies, BYOK, and spend limits for every customer | No documented end-customer object. Your app maps customers to OpenRouter scopes. |
Compliance | Merge is SOC 2 Type II, ISO 27001, GDPR, and HIPAA compliant | No public ISO 27001 or HIPAA claim |
Dedicated deployment | VPC and on-prem on Enterprise plan | No dedicated deployment option |
"Merge Gateway offers better LLM routing, cost control, and observability functionality than OpenRouter. We only gained net-new capabilities by switching."
